How?

Can someone explain to me how little boys (and not so little) can get pee to land only in the spot where the bolts are that attach the toilet to the ground? It's like the scene in JFK where Kevin Costner (I think it was him) explains how if there was only one bullet it would have had to turn in the air. There is no sign of pee anywhere else. Not on the shower curtain, or tub, or floor (sometimes it is there.) Somehow though, it ends up in that spot. The stream must bend in the air to get to just that spot. Surely there is a name for this phenomenon.
